SMITH AND ONE-FOURTH TO EGG-SHIPPING CASE.

To all whom it may concern Be it known that I, JOHN H. SPANGLER, a citizen of the United States, residing at Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in Egg-Shipping Cases; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention has for its object to provide an eflicient shipping case or carton, espeeially adapted for use in shipping eggs by parcel post, and which, while very light and of very small cost, will have the required strength and will so hold the eggs in suspension therein that they will not be broken even by the roughest usage encountered in shipping.

To such ends, generally stated, the invention consists of the novel construction and arrangement of parts hereinafter described and defined in the claims.

In the accompanying, drawings which illustrate the invention, like characters indicate like parts throughout the several views.

Referring to the drawings: Figure 1 is a plan View with some parts broken away, showingthe improved shipping case; Fig. 2 is a vertical section taken on the line :0 02 on Fig. 1; Fig. 3 is a transverse section taken on the line in on Fig. 1; Fig. 4 is a view in end elevation showing the filler or inside elements of the case, some of the said parts being separated from each other to illustrate the manner of assembling the same; Fig. 5 is a view in elevation; and Figs. 6 and 7 are perspective views showing the different kinds of elements used to make.

up the filler or inside structure of the case.

Referring first to Figs. 5, 6 and. 7, the.

numerals 1, 2 and 8, respectively, indicate the elements which make up the said filler or inside structure of the case. The case may be designed to hold any desired number of eggs, but as shown, it is designed to hold one dozen eggs, and the inside structure or filler thereof, is made up of five of the elements 1, three of the elements 2, and three of the elements 3. As preferably constructed,

the elements 1, which are called partition. plates, are of disk-like form, while the ele- Specification of Letters Patent. Application filed January 15, 1914.

ments 2 designated as trough forming plates, are bent into channel shape form in cross section, and the elements 3, which are designated ascover plates, are in the form of elongated [lat strips. ing the case may be made of any suitable material, but all thereof, are preferably constructed from heavy and still cardboard The disk-like partition plates 1 are formed with slits 1 that are arrai'lged in parallel pairs that extend nearly but not quite radially inward, and they are also formed.

plates 1. The manner of assembling the filler or lnner structure of the case is as follows:

First, the trough plates. 2, while properly bent into channel shape form, approximately as shown in Fig. 7, are slipped onto.

1 in such manner that their slits 6 embrace the portions between parallel slits 4t of such partition plates, and in such manner that the outer unslit portions are embraced by the said slits 4-. This inter- .locks the trough plates 2 to the partition plates in such manner that the said trough plates are held in proper form and the said trough plates properly space the partition plates. Otherwise stated, the said partition plates and trough plates, when thus assembled, mutually brace each other. The eggs may then be placed in the several partitions of the several troughs and the troughs may then be closed by sliding the cover plates 3 into the slits 4 in such manner that the slits 7 of the said plates 3 embrace the undercut parts of those portions of the partition plates 1 which are between the pairs of slits -l-. The cover plates, when thus applied, not only close the egg holding troughs but afford additional braces for spacing the partition plates and for further reinforcing the filler of the case. lVhen the said parts 1, 2and 3 are assembled and in? the several plates The elements formterlocked, as above described, they afiord a complete egg case or holder, but for the purpose of shipment of eggs by parcel post, would be too liable to be broken, and hence, not a satisfactory shipping case. Hence, I employ in connection therewith, an outside casing which may be cheaply made from a heavy and stiff sheet of cardboard 8 bent into cylindrical form and having radially inturned abutting edges 9 that are forced into radial slits 10 formed in the partition plates 1. When the outside casing is thus applied, it will be securely held to the partition plates and will not only reinforce, protect and strengthen the filler, but will afford an outer wall space outward from the egg holding troughs, and from which the egg holding troughs are so spaced that the eggs will be held in sort of suspended cradles where they will not be subject to any direct or substantially direct blows or jars. Preferably, caps 11 are slipped onto the ends of the cylindrical casing 8, and these serve to securely hold the outer casing 8 interlocked to the partition plates 1. The caps 11, it will be noted, are spaced from the outer partition plates 1. so that the latter will not be subject to direct blows received at the ends of the case. To make the intermediate portions of the compartments of the trough plates 2 exp'ansible so that they will closely fit eggs of difierent sizes, they are shown as provided with slots 12 at their angles.

In actual practice, this egg case has been found eiiicient, in all respect, as an egg carrying case or carton, for shipment by parcel post. It has also been found that it can be made in large quantities at an extremely small cost, in fact, at a cost considerably less than the cost of returning the same to the sender .by parcel post. An egg shipping case of this character may, therefore, be economically used for shipping purposes, even where it is used for only one shipment. It may, however, be used over and over again a goo many times. As already indicated, it may be made in difierent sizes for carrying a greater or less number of eggs. In fact, I have found that by increasing its diameter very slightly, its egg carrying capacity may be increased to carry two dozen or more eggs.

The case is primarily designed as an egg shipping case, but of course, it may be use for shipping other fragile articles.

\Vhat I claim is:

1. A shipping case comprising partition plates forming plates interconnected, trough forming different directions and spaced around the centers of said partition plates to form a plurality of circumferentially spaced egg receiving troughs divided into compartof the kind described and trough with the said .filler and spaced from plates extended outward in ments by said partition plates, and means closing the outer sides of the said troughs.
